These scripts both fail on me with a message "Java Virtual Machine
Launcher: Could not find main class. Program will exit". Any idea, what
I am missing here? This is on WinXP.

PS.: I have seen that I could instead download the provided and
pre-populated sample database here (which is what I am going to do until
someone responds to this append) but that is not the point, here. I
would like to be able to regenerate this entire demo natively.
